BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum x morifolium, typically grown as a cut flower Chrysanthemum and hereinafter referred to by the name ‘DLFSHAD3’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program is to create new cut flower Chrysanthemum plants with numerous attractive inflorescences.

The new Chrysanthemum plant originated from a cross-pollination in February, 2015 of a proprietary selection of Chrysanthemum x morifolium identified as code number db 34294, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum x morifolium identified as code number db 10460, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Maasdijk, The Netherlands in March, 2016.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings since March, 2016 in a controlled greenhouse environment in Maasdijk, The Netherlands has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DLFSHAD3’. These characteristics in combination distinguish ‘DLFSHAD3’ as a new and distinct Chrysanthemum plant:

-   -   1. Upright plant habit; uniform growth habit.     -   2. Dark green-colored leaves.     -   3. Uniform and freely flowering habit.     -   4. Strong upright flowering stems.     -   5. Daisy-type inflorescences with light purple-colored ray         florets and bright yellow green-colored disc florets.     -   6. Resistant to Fusarium and White Rust.     -   7. Relatively tolerant to high and low temperatures.     -   8. Good postproduction longevity.

Plants of the new Chrysanthemum differ primarily from plants of the female parent selection in ray floret color as ray florets of plants of the new Chrysanthemum are light purple in color whereas ray florets of plants of the female parent selection are light purplish pink in color. In addition, ray florets of plants of the new Chrysanthemum reflex with development whereas ray florets of plants of the female parent selection do not reflex with development.

Plants of the new Chrysanthemum differ primarily from plants of the male parent selection in ray floret color as ray florets of plants of the new Chrysanthemum are light purple red in color whereas ray florets of plants of the male parent selection are white in color.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum X morifolium ‘Chelo’, not patented. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Chelo’ in ray floret color as plants of the new Chrysanthemum have light purple-colored ray florets whereas plants of plants of ‘Chelo’ have darker purple-colored ray florets. In addition, ray florets of plants of the new Chrysanthemum are more convex than ray florets of plants of ‘Chelo’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph on the first sheet (FIG. 1) comprises a side perspective view of a typical flowering stem of ‘DLFSHAD3’ grown as a spray-type cut flower.

The photograph on the second sheet (FIG. 2) is a close-up view of upper (top of the photographic sheet) and lower (bottom of the photographic sheet) surfaces of typical leaves (left) and inflorescences (right).

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the late spring in ground beds in a glass-covered greenhouse in Maasdijk, The Netherlands and under cultural practices typical of commercial cut Chrysanthemum production. Plants were initially given long day/short night treatments followed by short day/long night treatments to induce flower initiation and development. During the production of the plants, day temperatures ranged from 18° C. to 25° C., night temperatures ranged from 20° C. to 22° C. and light levels averaged 8 klux. Plants were grown as single-stem spray-type plants and were eleven weeks old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
